24...Rg7 25.Kf2 

After the game, Komodo 10 also liked 25.Rf1 and 25.Re3, as well as the two other King moves that unpin White's g-pawn, 25.Kh1 and 25.Kf1. I made my choice based on the hope that, once I had won the d6 pawn, a centralized King would help escort my connected, passed "Jerome pawns".

25...Rf8 26.Nd5 Bg4 

27.Ne3

Afterwards, Komodo 10 suggested that my King further advance, with 27.Ke3. It then saw as most practical that the Bishop retreat and reposition, with 27...Bc8 28.Rd2 b5 29.Red1 Bb7 and things would still be relatively balanced. If I had to do it all over again, that would be my choice.

27...Bxf3 

Unexpected, but logical. Black returns his extra piece for a couple of pawns.

28.gxf3 Nxf3 29.Rh1 

Suddenly, all of Black's pieces are focused on White's King!

29...Nd4+

Best might have been 29...Nd2+ 30.Ke2 Nxe4 31.Rdf1 Re8 although most of the storm would have passed.

30.Ke1 

Probably leading to an equal game would have been 30.Nf5 Nxf5+ 31.exf5 Rxf5+ 32.Ke3, but I wanted to keep the Knight defender around, as it was doing a pretty good job.

30...Nf3+ 31.Ke2 

Here, I though to myself, So, he had a draw in hand, to back up his sacrificial attack...

31...Nd4+ 

Played too quickly, perhaps with the same idea in mind: Chase the King back to e1, check him again from f3: draw by repetition. But, in my musings I had overlooked the fact that this was not a discovered check, as before, so things have changed.

Instead, the Knight needed to go to g5, when White would still have a lot of work to do to convert his extra pawn into a win.

32.Rxd4 Black resigned

Lucky, me, this time.

I have one more Jerome Gambit, this round, against LittlePrince, who plays 3...Nf6, but who allowed a transposition after 4.Nc3 Bc5 5.Bxf7+. I have only played the Jerome a few times against players of LittlePrince's rating - and have not scored well (especially if you do not count the 4-move win on time) - but, here we go!

12...Nc4 

Of course. (I write that now, but the move came as a surprise.) White's Bishop is unprotected, and it's capture would lead to a brutal fork. At the same time, the b-pawn is available for capture.

13.Bd4 

After the game, Komodo 10 suggested 13.Qc1, to protect the Bishop and the pawn. Assessing 13...Nxe3 14.Qxe3, Black would have exchanged a piece that had moved 4 times for one that had moved once. On the other hand, White's Queen would be pulled onto the same file as Black's Rook, with a possible ...d5 coming.

The text move avoids the Knight-for-Bishop exchange, while threatening Bxf6 - as if the piece had moved to g5 in the first place (but taking an extra move).

13...a6 

After the game, Komodo 10 recommended 13...Nxb2 14.Qb1 Nc4 15.Qxb7, when White's Queen would be drawn dangerously far away from the Kingside, should Black choose to attack.

Was my opponent planning to support his Knight at c4 with ...b5 ? I thought so, but his next move suggested otherwise.

14.Ne2 Ne5 15.Nc3 

A craven attempt to suggest a draw, by repetition of position - another symptom of my bad emotional state. 

I got a chuckle out of the quick assessment that the Chess.com site provided, after the game, labelling both my 14th and 15th moves as "excellent". Black's response was best.

15...Nc6 16.Bxf6 gxf6 

Breaking up the Kingside pawn structure, rather than play 16...Qxf6, losing a pawn to 17.Rxd6.

17.Qd2 Qe7 18.Rad1 Rad8 19.Qf4 Kh8 20.Rfe1 Ne5

Black is not in a hurry. Let White take the risk and make the mistake.

21.Nd5 Qg7

Giving up a pawn to get the Queens off of the board. The alternative was 21...Bxd5 22.Rxd5 (planning pressure on the d-pawn down the file), when one of Black's Rooks, or his Queen, can go to either of the semi-open files; perhaps 22...Rg8 was best.

One line I never considered at the time was 21.Bxd5 22.Rxd5 f5!?, which would have revealed some of the structural problems of my Kingside after 23.Qxf5?! Rg8. More about this, later in the game.

22.Qxf6 Qxf6 23.Nxf6 Re7 24.b3

With 3 pawns for the piece, White has probably equalized. Black's pawn on d6 is still a weakness, and if White can get in c2-c4, he can apply pressure to keep things in balance.

I was catching my breath, but the game was going to take a wild turn.

Jerome Gambit: Folie a Deux (Part 1)

I won my third round game - an Italian Four Knights Jerome Gambit - in the "Italian game Classic" tournament at Chess.com, when my opponent and I seemed to have the same "hallucination" about a tense, tactical position. Up until then, I had been awkwardly struggling to lurch my way back to equality - only to be smacked around by a violent return of my sacrificed material.

Given the distracted level of my play, I consider myself quite lucky.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 

Whew! My game against Winawer99 in the same round continued 4...Nxe4, and I decided to avoid my past suffering with the Noa Gambit / Monck Gambit / Open Italian Four Knights Jerome Gambit - 5.Bxf7+ - and played, instead, 5.Nxe4 d5 6.Bd3 dxe4 7.Bxe4 Bd6 8.Bxc6+ bxc6 9.d4, a line that I also have struggled with. It showed: on my way to a possibly drawn Bishops-of-opposite-colors endgame, I overlooked a checkmate in 2 moves (0-1, 21).

5.Bxf7+ 

The Italian Four Knights Jerome Gambit.

What difference does the addition of Knights at c3 and f6 make, when compared to the regular Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+)?

Komodo 10 shows it to improve Black's position by about 3/4 of a pawn.

The Database has 2,731 games with the Four Knights version, with Black scoring 61%. This compares to 15,157 games with the Jerome, proper, with Black scoring 54%.

I have to admit, in my own games, Black scores 25% in my Italian Four Knights Jerome Gambit games (62) versus scoring 17% in my regular Jerome Gambit games (336). 

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Re8

I like this move. Instead of worrying which piece to save, Black develops another one, on a crucial file. Let White figure it out!

8.dxc5 

In preparing this post, I was amused to discover that Komodo 10's second choice, here, was not a capture, but 8.0-0, fully relying on the fact that not all of the pieces will be able to escape, e.g. 8...Bd6 9.f4!? Nc6 10.e5, etc. 

That line, in turn, raised a question for me: Has anyone ever tried moving the f-pawn right away, i.e. 8.f4 ? It turns out that The Database has two examples - Svirfneblin - cosmoo, blitz, FICS, 2011 (1-0, 24) and Mvskoke - Panico, blitz, FICS, 2012 (1-0, 36). It is an example of going too far, however, as Black has 8...Bxd4 9.Qxd4 Nc6 and he is doing better than in the normal lines.

By the way, The Database has 6 games with 8.0-0 (Black scores 56%) - and in 3 of them, Svirfneblin had the White pieces. I will have to look at more of his games...


8...Kg8 

Finishing castling-by-hand. I have noted

This is an improvement over 8...Nc6 of perrypawnpusher - hudders, blitz, FICS, 2010 (1-0, 13) and 8...Nc4 of the tragic perrypawnpusher - TrentonTheSecond, blitz, FICS, 2010 (0-1, 9),

9.O-O d6 10.cxd6 cxd6 

This is probably an improvement over 10...Qxd6, which I faced a couple of times perrypawnpusher - hklett, blitz, FICS, 2013 (1-0, 31) and perrypawnpusher - strandskatan, blitz, FICS, 2013 (1-0, 38). I was prepared, sort of

After the game Houdini recommended the dull 11.Qxd6 cxd6 12.Rd1 with pressure against Black's d-pawn, although Black is still better.

11.Be3 

An odd move; the Bishop usually goes to g5. I was planning to play f2-f4, but, for some reason I was worried about ...Qb6+ at some point, so I protected the a7-g1 diagonal. Of course, White's b-pawn is not vulnerable to that enemy double attack, until the Bishop moves. I suspect Caffeine Deficiency Disorder.

11...Be6 12.f3 

This is the move that White sometimes plays when he gives up on his plan to attack, and decides to hunker down and challenge Black to do something with his material advantage. Suddenly - comparatively, as the time control was 3 days per move - that became my plan.

The word "collywobbles" comes to mind.

Jerome Gambit: Yet, Ever Onward

The third round of Chess.com's "Italian game Classic" tournament has started, and I find myself in Group 1 - which consists of me, LttlePrince, pitman63, Sp1derR1c0 and Winawer99. (I am the next-to-lowest rated.)

With two Whites to start off with, I faced a couple of Two Knights Defenses, and was able to wrangle one of them into an Italian Four Knights Jerome Gambit.

The other game could have evolved into a Noa Gambit, but I haven't recovered the suffering I experienced at the hands of  RemoveKubab1, last year. (That is quite funny, given that Komodo 10 rates Black 3 3/4 pawns ahead in the Italian Four Knights Jerome Gambit; while it assesses Black to be only 1 1/2 pawns ahead in the Noa Gambit.)  I keep thinking that I should try the Boden-Kieseritzky Gambit, but will probably return to using a couple of ideas from Yury V. Bukayev.
